Millised on erinevused public, private, protected ja internal juurdepääsutasemetel programmeerimiskeeltes?

In C#, access levels determine the visibility of class members:

• public — accessible from anywhere.
• private — accessible only within the same class.
• protected — accessible within the class and its subclasses.
• internal — accessible within the same assembly, i.e., within the same project.

For example, if a class or method is declared as internal, it will only be accessible within the current assembly, even if other projects reference this assembly. This is useful for hiding implementation details within a library.
